MANUFACTURE OF CHANNELED AXLES.

SPECIFICATION formng part of Letters Patent No. L /1,544, dated March 29, 1892.

Application filed January 11, 1892. Serial No. 417,73Z. (No model.)

To all whom it may concern:

Be it known that I, ORLANDO CLIFFORD HALL, a citizen of the United States, residing at Auburn, in the county of Cayuga and State of New York, have invented certain new and useful Improvements in the Manufacture of Channeled Axles', of which the following is a specification.

My invention relates to the manufacture of that class of axles and aXle-blanks having longitudinal channels or grooves; and my invention consists in forming said grooves and preferably simultaneously shaping the exteriors of the aXles by subjectinga rectangular bar to the action of dies, as fully set for-th hereinafter, and also in the Construction of the dies to efEect the improved method of -manufacture.

In the accompanying drawings, Figures 1, 2, and 4: are views in part section illustrating' channeled axles of the forms desired to be produced. Figs. 3, 5, 6, and 7 illustrate in cross-section different forms of channeled aXles. Fig. 8 is a perspective View of a bar from which an aXle may be rolled. Fig. 9 is a sectional elevation of one form of mill which' may be employed. Fig. 10 is a View of the mill looking in the direction of the arrow, Fig. 9.

The aXle bar or blank to be formed may have any suitable external Outline or crosssectional form with a longitudinal groove or channel w. Thus it may be wider and deeper at the center and tapering toward the ends, with a channel at the top, as illustrated in Figs. l and 2, or it may be narrower at the center, as illustrated in Fig. 3, decreasing in depth toward the ends andincreasing in depth toward the center, or it may be wider and shallower at the center, increasing in depth toward the ends, as indicated in Fg. 4, and it may be rounded or substantially square in cross-section, as in Figs. 5 and 6, and may be thicker at the bottom than at the sides, as in F-ig. 7.

I do not here claim an axle having a groove or channel, as this constitutes the subject of a separate application for Letters Patent, Serial No. 417 ,7 31, the invention herein set forth relating to the manufacture of such axles or axle-blanks. In such manufacture I first roll molding.

or force or otherwise shape a bar B, Fig. 8, to

a substantially rectangular shape in crosssection and preferably tapering in both directions from the center toward the ends, although the shape of the bar will depend ot' course upon the external configuration of the axle to beproduced. In order to channel and properly shape said bar to make theimproved axle bar or blank, I subject it to the action of a rolling-mill in which there aretwo rocking or rotating rolls 3 4, the roll 3 carrying a die 5 and the roll 4 carrying a die 6, in which dies are grooves or chaunels y 'y', adapted to secure the proper conformation of the bar as it is passed between them. In the Construction shown the groove y' is adapted to shape the exterior of the bar, while the groove y of the die 5 has a longitudinal tongue e of such shape and so arranged that as the bar passes 7o between the dies it will indent the same, forming the groove x. It will be seen that the tongue ein acting upon the bar tends to spread the latter, and will thereby force it outward ,to fill the Outline ol' the pass, and thus facilitates the shaping of the bar in the process of In the Construction shown the end of the bar is introduced between the ends of the rolls 3 4 before they have turned sufficiently to bring the dies into proximity, after which the dies are brought to act upon the bar adjacent to the end, and the latter in passing between the dies is shaped from one end to the other. Instead of dies revolving continuously, as thus described, however, oscillating dies may be employed, as in rolling, tapering, and other axle-bar blanks. The ends of the bar may be t'ormed into journals 14 before or after or during the time that the bar is being acted upon to shape the same and form the channel, and the collars 13 may be formed by means of upsetting-dies either before or after the bar is acted upon to channel the same.

Without limiting myself to the particular Construction of dies shown, I claim- 1. The within-described improvement in the art of making axle bars or blanks, consisting in subjecting a rectangular bar to traveling pressure between dies provided withatongue oo e, substantially as set forth. 2. In the mauufacture of aXle bars or blanks,

subjectng a rectangnlar bar to the action of aXle bars or blanks, of rolls 3 4, provided with shaping-dies, With gro'oves adapted to impart dies 5 6, shorter than the peripheries of the the desired external shape to the blank, and rolls, one of the dies provided 'with a tongue with a tongue arranged to spread and ehane, substantially as described. I 5 5 nel the blank, substantially as described. I In testimony whereof I have signed my 3.
